PyCharm is logging to journal (systemd-journald) – why and how to disable it?

I see entries from PyCharm in my system journal logs (managed by `systemd-journald` and accessed with `journalctl`) like this:

`wrz 10 13:18:23 demon.sfx.local pycharm.sh[58022]: 2024-09-10 13:18:23,063 [8083716]   WARN - #git4idea.repo.GitSubmodule - Submodule not registered as (…)`
 

I don't remember seeing this in the past – has something changed in this regard?
I don't think system logs are proper place for PyCharm to use for its logs – how can I disable PyCharm logging to journal?
